To all 20710121, it nmy concern.-

Be itknown that I, WILLIAM THOMAS Suv- MOUR, a subject of the Queen of Great Britain, residing at Stockton-on-Tees, in the county of D urham, England, have invented certain new and usefulImprovements in Metallic or other Vessels and in (lovers Therefor, for which I have received Letters Patent in England, No. 1,876, dated February 7, 1887; in France, No.

No. 43,733, dated August 26,1887; in India, No. 97, (No. of 1888 register,) dated Januthe fulcrum for applying thelever to force up the cover or lid, to which it also affords protection from external pressure And in order that my invention may be fully understood, I will now proceed to describe it by referring to the accompanying drawings, in which sectional views of boxes or cans constructed and furnished with levers in accordance with my invention are illus- 10 185,301, dated August 12, 1887; in Germany,

ary 10, 1888; in Belgium, No. 80,565, dated February 1, 1888, and in Canada, No. 28,654, dated Feta-nary 7 1888;) and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in metallic or other receptacles-such as the tin cans or boxes ordinarily used for inclosing meat, tish, or other material, which boxes or cans require to be closed up securely, whether to exclude air or to endure the treatment to which they are usually subjected in packing and transmission from producer to consumer, and afterward require to be opened with facility. Boxes or cans employed for this purpose are often closed up by having the lid or cover soldered onto the rim of the box or can, which has to be ripped open to obtain access to the inside of the box or can. Attempts to overcome the objections to this mode of closing up this class of boxes or cans have resulted in constructing them with speciallyformed rims, into which speciallyconstructed lids or covers can be made to tit, so that a detached lover of a simple character can be ap plied to the under side thereof and employed to force the lid or cover from the box or can. The essential features of n1 y invention are a simple means of applying leverage to the cover or lid, combined with means for titling the cover or lid into the end of the box or can, so that by attaching the lever to the upper or outside surface of the lid orcover the rim of the said box or can which extends beyond the top of the lid or cover can be employed as trated in .l igures 3, and 5, the correspond ing views in plan being illustrated, respectively, in Figs. 2, 1 and 6.

In order to obtain a compact and close tit between the cover or lid a and the box or an Z), I turn up the edge of the cover or lid (1 to form the rim 0, which is inclosed within the corresponding rim, (1, of the box or can b, and in order to obtain the requisite degree of tightness in the tit between these rims and to facilitate the withdrawal. of the lid when required I prefer to give to these rims a slight and corresponding taper, the lid or cover practically forming a tapered plug inclosed by the rim d, the edge of which extends beyond the rim 0 and is rounded or wired over or otherwise rendered stilt, and serves both as a guard to protect the lid or cover from external pressure and as a fulcrum for the lever 6, which is shown in. the figures as permanently attached to the lid or cover a in. a suit;- able manner. A ledge, (1, forms a pl.ugseat within the box or can b in any suitable manner, such as that illustrated in Figs. 1 and 5, for fixing the position of the lid or cover (I when pushedinto the-box or can its proper distance; but I prefer as an effective and simple means of providing the requisite seat or ledge 11 to unite the rim (6 to the box or can b in the manner clearlyillustrated in Fig. 3, in which a difference is nrovided bot-ween the internal diameters of the box or can b and the rimd, which forms the ledge or seat (Z for the cover or lid (1, the rim (l being provided with a wire-shaped edge, (1 to make it stiff to serve as the fulcrum for lever e, and to protect the lid or cover it ted into it. lhe

advantage of this mode of fitting the cover to the can, in addition to that of simplicity of construction, is that such a ledge or seat, while serving its purpose of supporting the cover a, presents no obstacle to the discharge of the contents of the box or can, whereas when the seat or ledge forms an internal flange or projection eXteudin g into the box or can an ob-' struction is formed, which is detrimental to effecting a complete clearance thereof by atfording a lodgment tor a residue of the contents.

In order to force up thelid orcoverato open the box or can 7), which, it is obvious, cannot be done by any form of lever applied. to the under side thereof, one or more lovers, 6, are attached to the lid or cover a. Figs. 1 and 2 illustrate a box or can provided with one lever only. In Figs. 3 and 4 three levers are pror ided. Each lever fits into a socket, on,

secured to the lid or cover, to enable it to be turned over the rim or down on thelid,as required. In Figs. and 6 I illustrate at'orni ot' lever designedto turn round the circle, so as to be applicable at an y part of the circumference of the lid or cover a. providing a lever, c, precisely similar to the levers illustratml and described with reference to Figs. 1, 2, 3, and it; but instead of turning in a socket fixed in position near the edge of the cover or lid the lever is hinged to the bar 0., turning round on the pinf in the eentero'li' the lid or cover a. a is a flange extending over the lid or cover, so as to overlap the free end of the bar 0 to hold it down when resisting the strain produced by applying the lever c.

Having now destafibed my invention and in what manner the same maybe carried into e'liiect, what I claim is i 1. As a new and improved article of manu- 'lhis is effected by facture, a can orboxhaving its sides continued above its top, a seat-formed in the top thereof, and a cover resting therein provided with a lever pivoted thereto, whereby the said continued portion of the sides of the said can or box acts as a fulcrum for the said leverin the operation of the same.

2. As a new and improved article of manufacture, a can or box having its sides continued above its top and strengthened, a conicallyshaped. seat formed in the top thereof, and a cover resting therein provided with a lever attached thereto and bearing upon the said strengthened portion of the sides, whereby the cover may be withdrawn from its seat.

3. The combination, in a cover, of a flange, a, extending over the outer periphery thereof, a bar pivoted to the cover, the outer end of the said bar being held by the said flange, and a lever pivotally attached to said bar, as and tor the purpose described.

t. The combination of a cover having a flange, to, extending over the outer periphery thereof, abar pivoted thereto, the outer end of the said bar being held by the said flange, a can having its sides continued above its top and strengthened, a seat formed in the top of the said can in which the said cover rests, and a lever pivotally attached to the said bar and adapted to raise the cover, as and for the purpose described.

In testimony whereof I affiX my signature in presence of two witnesses.

WILLIAM THOMAS SEYMOUR.
